are two main types of cell division: (1) mitosis and (2) meiosis. (Balls 34) Most cells are produced by a process called mitosis. In mitosis‚ a cell divides and forms two identical daughter cells. (Prescott 102) Each daughter cell then doubles in size and becomes capable of dividing. Most one-celled plants and animals reproduce by mitosis. (Baserga Biology 56) This is also the way most cells in your body and multi-cellular plants and animals reproduce. Mitosis in animal cells takes place in four orderly

that are very tricky. They are mitosis and meiosis. Many people often get confused with the two about their functions. They both serve as mechanisms for cell division. However‚ quite significantly‚ they are very much different in fact and occur in different situations. Mitosis and meiosis take place in different places. This is one of the first major differences between the two. Mitosis takes place within somatic cells (cells that make up the body)‚ while meiosis takes place within gamete cells

Lab #3: Mitosis and Meiosis To investigate the processes of mitosis and meiosis. Cells come from previous existing cells. New cells are formed by cell division‚ which involves karyokinesis and cytokinesis. Karyokinesis is the division of the cell’s nucleus and cytokinesis is the division of the cytoplasm. Mitosis and meiosis are the two types of nuclear division. Mitosis results in body cells: the formation of an adult organism from a fertilized egg‚ regeneration‚ asexual reproduction‚

Title- Mitosis Abstract –For this lab there is no experiment to be done only questions to be answered. In this experiment we will categorize and count the cells to compute the mitotic index of the total root area. Introduction – The purpose of this experiment is to answer questions associated with the onion root tip photos that are pictured in the lab. The questions for this lab will be drawn from the discussion and review section at the beginning of the mitosis lab. Once that section has been

Mitosis and meiosis are the means by which reproduction takes place. Mitosis creates an exact duplicate of cell so that old cells can be replaced‚ such as in skin‚ hair‚ and bones. Meiosis allows a cell to unite one half of its genetic makeup with a cell from another partner to create an entirely new organism. Mitosis Mitosis is the process by which two daughter cells are formed‚ each containing a complete set of chromosomes. Mitosis is the process by which an organism creates new cells‚ such

Abstract: The question of the investigation is if lectin can induce mitosis in the cell of an onion root tip. The hypothesis is that‚ if the lectin does not induce mitosis‚ then there should not be a great change in the number of cells that undergo mitosis. The alternate is‚ if the lectin does induce mitosis‚ then there should be an increase in of cells in mitosis. The control group of the experiment had root tip treated with water‚ and the experimental had root tip treated with lectin. Upon the

Meiosis Modeling Activity Background Information Meiosis is the process by which eukaryotic organisms produce egg and sperm having half the genetic information (haploid) of the other cells in the organism’s body (diploid). You will notice some similarities to mitosis but some definite differences in meiosis that result in genetic diversity in the gametes as well as the offspring formed by the eventual fusion of the egg and sperm. Two of the most noted differences in meiosis are that 1) there

Biology March 5‚ 2015 Introduction In the Mitosis lab an onion root was observed under a microscope to observe whether or not cell division takes place. Also‚ whether cells replicate in order for it to reproduce. By observing the onion root under the microscope it allows many layers to be looked at through each cell division. The goal of Mitosis is the replication of cells to produce multiple like cells. The steps involved in Mitosis are what is known as the PMAT stages‚ which are the following:
